WATER-HEATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 408,008, dated July 30, 1889.

Application filed June 18, 1888. Serial No. 277.445. (No model.)

To all whom it may concern:

Be it known that I, JACOB FRIES, a citizen of the United States, residing at Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in \Vater-Heating Apparatus; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to an improved apparatus intended more especially to form a part of a stove such as is used ordinarily for cooking purposes. The object is to adapt a water-heater to such a stove without interfering with its other uses, so that the same fire may serve to heat sufficient water not only for ordinary bath-room and kitchen supply, but also to furnish heat for the whole or a large portion of the house by means of a system of piping. To accomplish this it is necessary to present a considerable amount of surface to the fire, and the apparatus herein described is therefore designed to have both direct and indirect heating-surface.

Figure 1 is a cross-section of a cook-stove, showing my water-heater in position, the section of the latter being through 0 I) of Fig. 4. Fig. 2 is a plan of same with lids and grate removed, indicating the position of the apparatus. Fig. 3 is a View of the water-heater detached, being a section through A B of Fig. 4. The horizontal section is represented as not drawn down to its proper position on the vertical section. Fig. -1l is a plan of the water-heater, a portion of the horizontal section being cut away to show the top of the vertical section in full. Fig. 5 shows the vertical section cut through 0 D of Fig. 4, a horizontal section being represented in this View which is not intended to be brought into contact with the vertical section, but to communicate with it through similar pipeconnections. Fig. 6 shows a modified form of my water-heater.

A represents a cook-stove or range having a front plate A without any opening, the

usual ash-pit and other necessary doors being shown on the same side with the ovendoor. This plate A is some distance from the grate A, the object of the arrangement.

being to provide sufficient space for placing in position the water-heater, which I am about to describe, a similar space being also provided on the left-hand side. I The top A of the stove is preferably somewhat higher above the grate than usual.

The water-heater is represented as formed in two parts E and F. The part F is vertical and shaped in plan like the letter L, one side or arm forming the front wall and the other the side wall of thefire-pot when in position. It is cast with corrugated sides F for the purpose of increased strength and heatingsurface, and wrought-iron vertical tubes F arranged in staggered form, are tightly secured top and bottom, sufficient waterspace being left between them and the corrugated sides. The part E is L-shaped in plan to correspond with the vertical part F, and in section it also forms a hollow L, having a slanting plate E and a narrow base E so shaped that when placed upon the part F its seat is outside of the tubes, the plate E slanting upward and inward from the outer edge of the tubes, which are thus left entirely open. These two parts are connected by means of pipes II and nipples G. The pipes are threaded right and left handed at opposite ends, the projecting roof of the upper part being tapped to suit one end and the hollow lugs F on the inside of the vertical part F to suitthe other end. The two parts are drawn together by means of these pipes, and the nipples G are then inserted through the hollowlugs E communicating with the water chamber, and screwed through the threaded lower end into the hollow lugs F, the top openings in the lugs E through which the nipples are inserted and screwed into position, being subsequently closed by plugs G.

The complete heater having been placed in position in the enlarged chamber of the stove, as previously described, the horizontal partE is directly under the top plate and its inner edge extends to the edge of the pot-holes. The vertical section forms a side and an end wall of the lire-pot and extends a considerable distance below the grate. An inlet-pipe K branches off into pipes J, which are connected to the lower end of the vertical part F, and an outlet-pipe L is connected to the top of the horizontal part E. These cocks are not shown. The pipe L conveys the heated water to the system of piping and radiators distributed throughout the building, while the inlet-pipe K returns it again to be reheated. WVhen in operation, it will be seen that the fire is in direct contact with a portion of the inside walls of the heater, so that there is a large direct heating-surface in the vertical section. The horizontal part E, which overhangs the fire considerably, furnishes very valuable direct heating-surface, and when the direct outlet to the stack is cut off by means of a suitable damper, (not shown,) as is commonly done when it is desired to heat the oven, the products of combustion are deflected down by the slanting plate E and pass through the tubes F to the smoke-flue A bending around the oven, from which it is separated by the partitions A and thence to the stack A The dampers A and A can be used to further regulate the r passage. The end of the heater below the fire, into which the water returns to be reheated, is thus kept hot, although the water in the horizontal section E, which is exposed direct to the fire, is

' much hotter, and thus maintains positive and active circulation throughout the system. A removable plate A under the vertical part of the heater permits the latter, as well as the smoke-flue A to be readily cleaned.

In the arrangement as so far described the products of combustion are compelled to pass entirely through the tubes to the smoke-flue A on account of the contact between the upper and lower parts E and Falong their outer edge. This, however, is not essential, as they may be made to pass around the vertical section F, as well as through the tubes, by keeping the horizontal section clear of the vertical, in which case it may be made as shown in Fig. '5; or the horizontal section may be made in one piece with the vertical, and the communication with the passage A be made through horizontal tubes F, as shown in the modified form represented in Fig. 6.

WVhat I claim as new, and desire to secure by Letters Patent, is as follows:

1. Thecombination, with a stove having an enlarged fire-chamber, a smoke-outlet communicating directly with said fire-chamber, a damper between said chamber and outlet, and a smoke-flue underneath the fire-grate, all substantially as described, of a water-heating apparatus having a vertical water-chamber forming a wall or walls of the fire-pot and extending below the grate, the products of coinbustion being brought in contact with said water-chamber when diverted downward to pass through said lower smoke-flue, substantially as and for the purpose set forth.

2. The combination, with a stove having an enlarged fire-chamber, a smoke-outlet communicating directly with said fire-chamber, a damper between said chamber and outlet, and a smoke-flue underneath the fire-grate, all

. substantially as described, of a water-heating apparatus having a vertical section forming a wall or walls of the fire-pot and extending below the grate, a horizontal section overhanging the grate, and passage-ways below said horizontal section between the fire-box and said lower smoke-flue, whereby the products of combustion are brought in contact with said vertical section when diverted downward to pass through said lower smoke-flue, substantially as and for the purpose set forth.

8. The combination,with a stove having an enlarged fire-chamber, a smoke-outlet communicating directly. with said fire-chamber,a damper between said chamber and outlet, and

smoke-flue underneath the fire-grate, all

substantially as described, ot a water-heating apparatus having a vertical tubular section connected to a separate horizontal section, the two being in contact on their outer edge and the horizontal section projecting over the open top of the tubular section, substantially as and for the purpose set forth.

In testimony whereof I afliX my signature in presence of two witnesses.

JACOB FRIES.
